# gotop

Another TUI graphical activity monitor, inspired by [gtop](https://github.com/aksakalli/gtop) and [vtop](https://github.com/MrRio/vtop), this time written in [Go](https://golang.org/)!  
Built with [gopsutil](https://github.com/shirou/gopsutil), [drawille-go](https://github.com/exrook/drawille-go), and my own [fork](https://github.com/cjbassi/termui) of [termui](https://github.com/gizak/termui).
